I have a question about an English phrase; please advise

remarks on revisions Notes on the revisions

““Remarks on revisions” refers to making markings on the changes made in drawings or documents such as P&IDs, data sheets, and vendor prints; in written terms, this is known as “modification marks”. The common practical method in the engineering design process is to place a triangular mark next to the sections that have been modified in the drawings or documents, with the version number – 1, 2, 3 – recorded inside it. . . . , indicates which version has been modified. Generally, foreign engineering companies require that this be clearly indicated on the drawings and data sheets. So that those involved in the project can clearly see what changes have been made between each version of the materials. I’d like to say hello to the friends on the second floor here, quoting your explanation. Please forgive any imperfections; this is intended solely for academic exchange. I’m sorry. “The English term for “Revision Description” is “Modification Description” or “Revision Statement”. It is a written description of the changes made to the drawings, especially those related to P&IDs. For example: 1. The gate valve on pipeline XXXX should be changed to a globe valve ； 2. Disable the impeller vibration sensing and alarm system of the air cooler ； 3. Add a minimum return line at the outlet of pump XXX ； . . . . Generally, large international engineering companies do this, which is called “Management of Change”” ； In domestic design institutes, it is generally called a “modification notice”.

What did that beginner say? ““Give your opinion on the revised version.” You’re hiding even this? Do you want to get extra points?

I’d like to share some opinions as well: the second floor provided an answer, the third floor was a bit mysterious, the fourth floor gave a detailed explanation, showing some research and effort in this area, the fifth floor had its own opinions, and I have learned a lot from this. In short, I think the Haichuan forum is really good. I came across it quite early on, but didn’t pay much attention to it; now, as I’ve delved deeper into it, I like it more and more and can hardly do without it. Everyone, I wonder what your thoughts are. This is how I think; please forgive me.

The explanation for the revision is exactly that

Version annotations or upgrade explanations for design documents such as specification sheets/drawings/data sheets/manufacturer information, etc. For example, Version P is the temporary version, Version 0 is the inquiry version, Version A is the procurement version, and Version B is the final version.
